Warth was from Space Sector 0002 and became the second person to be initiated into the Blue Lantern Corps. Each Blue Lantern was chosen by the Blue Lantern of the previous sector and brought to the Guardians of the Blue Lantern Corps, Ganthet and Sayd to be evaluated so they can truly judge whether they are worthy to become a member of their Corps or not. He was brought to the Odym, home planet of the Blue Lantern Corps, by its first member, Saint Bro'Dee Walker of Space Sector 0001. Warth spent several days with the Guardians while they evaluated and judged him for themselves. They explained to him what it truly means to be a Blue Lantern and join their cause.
